GEORGE OLIVER, OF CHARLOTTE, NORTH CAROLINA, ASSIGNOR TO THE CHARLOTTE OIL COMPANY, OF SAME PLACE.

OIL-PRESS CLOTH.

SPECIFECATION forming part of Letters Patent No. 317,003, dated May 5, 1885.

Application filed April 1, 1855. (N0 model.)

To aZZ whom it may concern.-

Be it known that I, GEORGE OLIVER, a citizen of the United States, residing at Charlotte, in the county of Mecklenburg and State of North Carolina, have invented a new and useful Improvement in Oil-Press Cloths used in Extracting Cotton-Seed Oil or other Oil by Pressure, of which the following is a specification. My invention relates to improvements in oilpress cloths which are used for inclosing the crude material, in order that it may be handied before it is put into the main press, and also as a strainer through which the oil may escape while the crude material is held under pressure.

The object of my invention is to avoid tearing the cloths in the main press. I attain this object as follows:

Referring to the drawings, Figure 2 represents a section of two boxes or plates of the main press, showing the manner in which the cake A is put into the boxes to receive the pressure, and the heavy black line B B represents the cloth folded around the cake.

The plate C is perforated to admit the passage of oil after its passage through the cloth.

E in Fig. 2 shows a groove through which the oil flows out.

Fig. 1 shows a sectional elevation of one box or plate, in which C is the perforated plate, and E E, &c., the grooves for oilpassages.

General experience has demonstrated that when the press-cloths are made of cotton they split at the ends, as shown by the marks F F, &c., Fig. 3, and when they are made of wool or camels hair they break at the points G G, Fig. 2, Where they foldover the ends of the cake, and as shown at the lines H H, &c., in Fig. 4.

I have found that if the cloths are made of cotton in the middle part and of wool or camels hair at the ends, as in Fig. 5, the middle part, K, being of cotton and the ends L L of wool or camels hair, the difficulties of tear- 5 ing in the above ways are entirely or largely overcome.

'W'hat I claim as my invention is- A press-cloth made up of cotton cloth in the middle part and of woolen or' carnels'hair cloth at the ends.

GEORGE OLIVER.
